不同食用方式下蝉花麦角甾醇、虫草素、腺苷和多糖的比较

开展对蝉花不同食用方式下其子实体、菌核、浸提液和浸提后蝉花,进行麦角甾醇、虫草素、腺苷和多糖的定量研究,以期得出有实用价值的差别性数据,为对蝉花进一步的综合利用提供理论数据。不同食用方式分为直接食用蝉花粉末、水煮后制剂和水煮后蝉花整食。根据市场上将蝉花质量高低按子实体大小划分,分别开发食用蝉花子实体、蝉花菌核、蝉花浸提液和浸提后蝉花。研究结果表明:(1)麦角甾醇。子实体中为0.34±0.05 mg·g~(-1),浸提蝉花中为0.31±0.03 mg·g~(-1),菌核中为0.07±0.01 mg·g~(-1),浸提液中未检出。(2)虫草素。子实体中为0.54±0.04mg·g~(-1),浸提蝉花中为0.28±0.02 mg·g~(-1),浸提液中为0.37±0.03 mg·g~(-1),菌核中为0.14±0.02 mg·g~(-1)。(3)腺苷。子实体中为0.61±0.04 mg·g~(-1),浸提蝉花中为0.35±0.05 mg·g~(-1),菌核中为0.30±0.06 mg·g~(-1),浸提液中为0.45±0.04 mg·g~(-1)。(4)多糖。菌核中为(14.84±1.79)%,浸提蝉花中为(13.34±0.95)%,子实体中为(13.17±1.02)%,浸提液中为(9.61±0.71)%。结果显示,蝉花子实体、菌核与浸提前后蝉花活性成分存在差异。

Comparison of ergosterol, cordycepin, adenosine and polysaccharide with different preparation methods in Isaria cicadae Miquel

In order to obtain useful and differential data and provide some theoretical data for further comprehensive utilization of the Isaria cicadae Miquel, we investigated the effects of different preparation methods including eating Isaria cicadae Miquel powder directly, drinking the leach liquor after boiling the Isaria cicadae Miquel with water, and eating residue after boiling the Isaria cicadae Miquel with water on the contents of ergosterol, cordycepin, adenosine and polysaccharide in Isaria cicadae Miquel. The Isaria cicadae quality was determined by sporocarp size on the market. This experiment was to develop food separately for sporocarp, sclerotium, leach liquor and digestion Isaria cicadae Miquel. The results showed that: (1) the content of ergosterol was 0.34±0.05 mg·g^-1 in sporocarp, 0.07±0.01 mg·g^-1 in sclerotium, 0.31±0.03 mg·g^-1in cicada flower after water extraction, but it was not detected in decoction; (2) the content of cordycepin was 0.54±0.04 mg·g^-1 in sporocarp, 0.14±0.02 mg·g^-1 in sclerotium, 0.28±0.02 mg·g^-1in cicada flower after water extraction and 0.37±0.03 mg·g^-1in decoction; (3) the content of adenosine was 0.61±0.04 mg·mL^-1 in sporocarp, 0.35±0.05 mg·mL^-1 in cicada flower after water extraction, 0.30±0.06 mg·mL^-1 in sclerotium and 0.45±0.04 mg·mL^-1 in decoction; (4) the content of ?polysaccharide was (14.84±1.79)% in sclerotium, (13.34±0.95)% in cicada flower after water extraction, (13.17±1.02)% in sporocarp and (9.61±0.71)% in decoction. The results showed that there are different active components in Isaria cicadae sporocarp and sclerotium, which would make more pertinent in resource utilization of ergosterol.
